I am so hurt by this

I was married to a man for ten years.

When we first got together there was this girl, Molly, that was super flirty with him. It was someone he had already known but after we married, I expressed how it was inappropriate and she should be dropped. (She would call him all sorts of pet names like baby etc) and he did no questions asked. Well over the course of the ten years, this girl would pop back into our lives. Always when we were not doing well. We split up at some point about 4 to 5 years in and we got back together 10 months later. I found out that during this time, they were extremely flirty..calling him handsome and her beautiful etc. I said again "she wants more and clearly so do you. we are together and married, she is not a friend..she has to go". He fought me on it for a long time and she tried so hard to convince me that she only saw him as a brother type thing. But, mean while the whole time I am with my husband.. she is talking to him behind my back and talking bad. "She will never be anything. She clearly uses you. I had to delete her off Facebook cause I couldn't stand watching her blow all your money. She is a shitty mom" etc etc. During this point, he was deployed and I worked 2 jobs..1 full time and one that i didnt get off until 3 am most times.

I knew better. I knew there was always more.

Fast forward 3 more year and another child later..we are again not together but real on and off at this point trying to figure out what we want. We decide to keep fight for our marriage but still live apart. This time, Molly was in the picture even more. They had plans to screw and sexted etc. I fought and fought for him to cut her off again. No matter how much i cried, he tried telling me how she is a "friend" and he is not cutting her off. He finally agreed after a sit down with my dad. So he said..phone records said other wise.

We were only back together this time around 4 months before we just decided we couldn't do it anymore...I decided I couldn't do it anymore.

That following summer, he BEGS me to work it out. He begs me to PCS (military transfer) with him. He tells me how in love with me he is and how he can't not have me and our kids. He tells me how he is going to counseling alone and with our daughter..that he is trying.

I tell him the chances are slim but we start being around each other a little more. He knew my only rule was no Molly. There was no room for her in our life if he wanted me.

He is over for dinner one night. He is helping me clean dishes and his phone buzzes. I glance over out of habit and it's just his dad. Then it buzzes again..this time..it is Molly.

I very quietly just walk away. He follows me soon after and asks what is wrong. I kindly tell him that I need him to leave and why. He flips put of me. I text her and tell her I'm done..she can have him.

He had the nerve to tell her "she stopped by my place for something and saw your name on my phone."

He flat out lied...he was having dinner in MY home because he was trying to win me back.

Anyway...that was the very end of it. I met a man soon after and we have been together since.

My ex and I have had an amazing coparent relationship this past year. We get along so well and we do everything in the best interest of the kids. We never belonged together and we realized that.

Well I called him the other day and I let him know I was expecting another child. He congratulated me but was understandably off a little.

Then he informed me that he is talking to her again..with hopes of it being serious and her moving to our state one day... he didnt want to tell me but since I told him I was pregnant he did....yall, I cant have this woman in my kids life. For years, I had her waiting like a vulture to swoop in. For years she disrespected in any way she could.

He was wrong and that is why I'm not with him but he is their dad so we had to make life work..but her..she will always be the other woman to me. No matter how much I pleaded to her for her to leave my marriage alone..she never cared. She basically laughed in my face.

All I can do is pray it fails..pray she doesnt ever move to our state.. I can handle a lot but I can't handle her having anything to do with me kids.
